Mrs O's Mystery; fabrics for Nana's Surprise MQ7 step 3 frame

This is what I have ready step 3 with a frame. My borders are going to be a pieced piano border; I used the 9.5" pieces sewn together then cut them in half. I am playing with the idea of adding a piping or flange between the red ho ho fabric frame & adding the 2" eggshell (KONA) border to the strip of keys. I have drafted a piano key border with some leftovers as a border as well, I'll see what I like best. but for now this is all pressed and ready on Mother's wall.
